From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux supports secure boot so if a distro supports it it's worth using it.
Linux can use a key signed by Microsoft in a preboot loader and then itself perform its own key authentications for all other processes and software (a shim), forming a secure chain from the BIOS up during boot. You dont have to play with creating your own keys.
So if your OS supports secure boot it is worth using it for added security at boot. Its far from perfect in this set up (as there are plenty of windows OS that also have permission to boot) but it is better than a free for all without it even if the risk is low for most desktop users.
You can go further and generate your own keys and use secure boot and TPM together to lock down the system further but you dont have to to get some benefits from secure boot.
That's not the question though. This is an average user installing Mint. They're probably not enrolling disk encryption with TPM values or SB certs, they're literally asking if it's going to help them by default, and the answer is no. Now, if they were asking how they could increase system security with Secure Boot, I'd answer differently.
